By adopting the vacuum formed by the drop leg extraction, and also with the help of the filtration media, disc filter separates the solid and the filtrate and gets filtrates in different quality divided by the distribution valve. It is widely used for white water recycling and pulp thickening. When used as saveall, it recycles water and fibers; when used for thickening, it achieves high production rate with low fiber loss via unit machine. Outlet consistency can reach to 12%~14%.

Design features:

Disc with different structures and high strength, ensures larger effective filtering area. It is economical and easy to replace.

All models and sizes are available. Filtering area can be modified upon capacity requirements.

Distribution plates are made of special wear resistant material, which has good seal effect.
